MERV ratings are used to rate the ability of an air conditioning filter to remove dust from the air as it passes through the filter. MERV is a standard used to measure the overall efficiency of a filter. Higher MERV ratings mean fewer dust particles and other airborne contaminants pass through the filter.

MERV ratings range from 1 - 16 and measurements are in microns. Some of the common particles related to MERV ratings are pet dander, insecticide dust, smog, dust, viruses, wood, tobacco smoke, spores, dust mites, bacteria and pollen.

Many of the common flat fiberglass filters found in residential use only have a MERV rating of 1 to 4. These are typically disposable panel type filters and do not do a good job of filtering the air because they will not stop particles smaller than 10 microns. They are designed to help protect your equipment, but do not provide adequate filtration for human needs.

Filters with a MERV rating of 11 (our best choice) are used in many commercial and industrial applications and will reduce particles in the 0.3 micron range and up. These filters are the best choice for homeowners who want the best dust control possible.
When using filters with MERV 8 ratings and above it is important to clean or replace them when recommended by the manufacturer because they will have a negative effect on air flow when they become dirty. This can lead to performance problems and decreased operating efficiency. To prevent your equipment from potential harm, we recommend your filter to be changed every 30 to 60 days.
The U.S. Department of Energy estimates that regular air filter changes will save you 5-15% on your heating and cooling costs each month! This is because changing your air filter regularly ensures that your HVAC system can operate at its highest efficiency, requiring less energy to push air through your home. This can be a savings of $10-$30 every single month for many homes.
